In Outlook 2003 adm you can´t unfortunately configure Outlook Anywhere settings and I done it with old school procedure:

Open GPMC and make a new GPO, go to GPP and execute wizard, go to fins a a desktop computer with Outlook well configured, and import from HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook\13dbb0c8aa05101a9bb000aa002fc45a the following entries:

“00036623”= Enable Exchange Proxy settings and control various check boxes.
“001f6622″= For specifying Exchange proxy server name
“001f6625″= For specifying Exchange proxy server name according to principal cert name.
“00036627”= For Authentication – Basic or NTLM

Take care that is posible that users has various Outlook profiles. Then you need to add the same but changing the registry path HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook\13dbb0c8aa05101a9bb000aa002fc45a in subfolder Outlook by other name profile.

Also, you can configure targeting in every configuration path for only apply to users that has an existent profile.

When you upgrade Exchange 2010 to SP2 can be that Exchange Shell disappears and I had to register manually.

Verify that the files exist ConnectFunctions.ps1 , RemoteExchange.ps1 y CommonConnectFunctions.ps1 on %ExchangeInstallPath%\bin (if not, as was my case, you have them in the installation folder \setup\serverroles\common)

Create a shortcut in %SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe -noexit -command “. ‘%ExchangeInstallPath%\bin\RemoteExchange.ps1’; Connect-ExchangeServer -auto” eliminating the start in. If you want the icon was (in my case) in %SystemRoot%\Installer\{4934D1EA-BE46-48B1-8847-F1AF20E892C1}\PowerShell.exe

I also put in the start menu folder within Exchange … to look like it never went.

In regedit must add several folders I attached the export of the same, you have to add them in [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns]. And ready, no need to restart (although I did just in case) are in the attachment but if the Exchange delete it, I give you a copy paste of records.
